CVE-2025-54816
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThis vulnerability occurs when a WebSocket endpoint does not enforce proper authentication mechanisms, allowing unauthorized users to establish connections. As a result, attackers can exploit this weakness to gain unauthorized access to sensitive data or perform unauthorized actions. Given that no authentication is required, this can lead to privilege escalation and potentially compromise the security of the entire system.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is an authentication bypass vulnerability where a WebSocket endpoint does not enforce authentication, allowing any user to establish a connection without credentials. Attackers can connect and potentially access sensitive data or perform unauthorized actions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify WebSocket endpoint exposureReview your network configuration and running services to determine if a WebSocket endpoint for Evmapa Evmapa is exposed and accessible on your network. Check service listening ports and any reverse proxy or load balancer configurations that may expose WebSocket routes.Affected if A WebSocket endpoint for Evmapa Evmapa is accessible from your network without authentication controls at the network layer.
-
Locate WebSocket configuration filesSearch your Evmapa Evmapa installation directory for configuration files that define WebSocket endpoints, authentication settings, or connection handlers. Look for files related to websocket, socket, or realtime connections.Affected if Configuration files exist that define WebSocket endpoints without authentication enforcement rules.
-
Examine authentication settings for WebSocketInspect the WebSocket configuration or source code to verify whether authentication mechanisms such as token validation, session checking, or credential exchange are implemented before allowing connections.Affected if The WebSocket endpoint lacks authentication enforcement logic or allows connections to proceed without valid credentials.
-
Test unauthenticated WebSocket connectionUse a WebSocket client tool (such as wscat or a custom script) to attempt a connection to the Evmapa Evmapa WebSocket endpoint without providing any credentials or authentication tokens.Affected if The connection is successfully established without requiring any form of authentication.
Your environment is affected if the Evmapa Evmapa WebSocket endpoint is accessible and accepts connections without requiring authentication credentials.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper authentication mechanisms (such as token validation, session checking, or credential exchange) on the WebSocket endpoint before allowing connections.
